Detailed Description
The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.
As shown in fig. 1-2, the simple and easy support for fast assembling and disassembling an urban overpass provided by the utility model comprises a vertical column 1, a transverse support 2 and a construction platform 3; wherein, the three upright posts 1 are vertically arranged at intervals in a triangle shape; a plurality of transverse supports 2 are connected between the middle parts and the lower parts of two adjacent upright posts 1; the construction platform 3 is arranged at the tops of the three upright posts 1.
The upright column 1 is made of a steel pipe with the diameter of 219 mm.
The transverse support 2 is made of 20a I-steel.
The construction platform 3 is a tripod made of double-spliced 20a I-shaped steel.
The simple and easy support of fast assembly is demolishd to city overline bridge still includes and sets up the steel sheet as the basis at three stands 1 lower extremes.
Will now the utility model provides a city overpass demolishs application method stand of simple and easy support of quick assembly as follows:
the upper part of a certain overpass bridge to be dismantled adopts a steel box girder as a main girder, a single-box single-chamber double-cantilever section is provided with plate type cross connections every 2m or so, and the total width of the bridge deck is 5 m. The total length of the main bridge is 75.5 m. The lower part structure adopts a phi 820 multiplied by 14mm circular steel tube pier stud, and the pier foundation adopts reinforced concrete. The full-bridge is provided with 6 steel stairs.
In the dismantling process, when the connecting part of the steel stair and the main beam is dismantled, the simple support is arranged at one side close to the steel stair, so that the upper end of the simple support props against the main beam, and if the height is not enough, one or more steel plates are arranged at the lower end of the upright post 1; then cutting off the connection between the steel stairs and the main beam, then removing the steel stairs, and then removing the main beam.
